What Schumag does
Schumag, operating today as SCHUMAG Precision GmbH, is a German precision metal-components manufacturer founded in 1830 and headquartered in Aachen. The company produces high-precision steel parts with diameters from 0.1 to 80 mm and tolerances down to 0.5 μm, executing complex in-house process chains of up to 30 steps spanning soft machining, heat treatment (including case hardening, vacuum hardening, gas nitriding, salt bath nitriding/QPQ), fine machining (centerless, surface, internal, and between-centers grinding, lapping, honing, superfinishing, hard turning, hard milling, micro grinding, abrasive flow machining), deburring (thermal, abrasive flow, ECM, sinker EDM), 100% inline inspection, and assembly. Production runs from 20-piece prototypes to 1,000,000-piece serial lots, with annual capacity of up to 60 million parts from a 39,500 sqm facility housing 360+ machines.
The company serves six primary verticals: industrial and heavy machinery (diesel engines, hydraulic components, construction equipment, cranes, rail vehicles — with named customers Caterpillar and Liebherr), defence (100% German/European supply chain), medical technology (surgical instruments, diagnostic devices, minimally invasive devices, dental, orthopedic), e-mobility (steering, brake, chassis components outside the drive train), automotive/engine (combustion and commercial vehicle components), and after-market spare parts (OEM-quality discontinued parts). Notable end-customers include Caterpillar, Liebherr, and Google (components for data-center backup power units). The business model is quote-based B2B contract manufacturing with multi-year contracts, priced on part complexity, quantity, and process requirements; no public pricing exists. Go-to-market is direct enterprise sales through a dedicated sales team and vertical-specific business development (e.g., Medtech). The company holds ISO 9001, ISO 14001, ISO 50001, and IATF 16949 certifications and exports to more than 20 countries.
Following a self-administered restructuring (Eigenverwaltung) initiated in October 2024 and successfully completed in January 2025, the prior SCHUMAG AG was replaced on February 1, 2025 by SCHUMAG Precision GmbH under a new investor group led by Amsterdam-based Active Capital Company with regional partners Nomainvest, TPPI, and CoDa. CEO Stefan Lepers, alongside Managing Director Oliver Tack, leads the company under a 'Mission 2030' strategy targeting expansion into new markets and a younger workforce. Headcount is approximately 400 employees as of 2024/2025.
